COAL Bemanning vEen'rrr/rinvii*` Application med necemberiaiesi. semina. 581,228.1

The device forming the subject matter of this application is adapted to be used for makingv briquettes ofthe hind which are Y.

composed of finely divided coal, vand* a binder, such as asphalt. One objectof the invention is to provide novel means for securing a uniform ilow of thezmixture toward the briquetting rolls.

Another yobject of the invention is to im-` prove the lconstruction of the gate which regulates the flow of the mixture to the briquetting rolls. A still further object of the invention is to supply novel means forv operating the gate.` f

It is 4within the province of the disclosure to improve generallyand to-enhance the utility of devices of that type `to whichvthe invention appertains.

vVith the above and otherobjects in View,

. which will appear as the description proceeds, .the invention resides in the combinationv and arrangementv of parts ,and in the details of construction hereinafterdescribed and claimed, it beingk understoodl that 25 changes in the precise embodimentfof the invention Y herein disclosed, may be. .1 nade Within the scope of what is claimed, without departing from vthe spiritk of theinvention..

As an adjunct to the invention claimed, therek is provided a mixing chargingciinely divided coal. l

A. box-like hopper-head 10`is secured to the mixing device 1, about the outlet 6. The

- '50 hopper-head 10 comprises aforwardV wall device l, dis-1l 1lwhich is downwardly and rearwardly inf clined.

After-the' coalY and the .asphaltv binder have been mixed 'in the mixing device 1, the' material passesnthrough the outlet (i and is received on the wallv 11 oft thehopper-head 10, and moves into a hopper-,14, which is secured to thelewer end of the head 10. The hopper 111 isqarranged vertically, or nearly so. l Fig.r2 ,shows that the hopper 14 yis .of rectangular cross'section. `The hopper 111 has a` slidably mounted, kvertically adjustable wall 15, 'under thecontrol Vof lan adjusting means, such asfa headedscrewv 16, journaled-inthe projecting ledge ofthe top ofv the hopper-head 10, and threaded into an outstanding liponthe upperend of the wall 1,5, Fig. 2shows that thelvertical internal corners ofthe hopper 14 are rounded and concaved, as shown at 17.

In order that briquettes of even-hardness and uniform quality may be made, it is lnecessary to feed the mixture evenlyfto the ,briquettingpress, hereinafter described; Ay feed that is heavier or harder near to the f centerof the press than at the sides ofthe press willfcause thev briquettes toA beh-made ytoohard at-the centerand too softgaround the,v periphery,ja briquette of uneven tex- .ture,'as to hardness, being an articlewhich 8 0 discriminating trade will reject. 1., Because therefore,` is not greater thanelsewhere, the

mixture lowsdown evenly, and a uniform]- i feed to the briquetting pressyand morefes- 90 pecially to the, gate,' hereinafter described,

results. Y

- Carried by `the.,frame181015 the briquetting press are vertical'platesl 19and on the inner surfaces of theplates there are down`- 95 Wardly c and inwardly linclined guides 20.

The: numeral 21 designates lapslidably mounted gate,-adaptedto movealong the downwardly and inwardly inclinedlower edge 22net. the-hopper 14, so aste regulatewo e the space between the inner edge of the gate and one of the rolls 23 of the briquetting press. Fig. 7 shows that there are recesses 24 in the upper.V surface ofthe gate 21, at the outerV edges thereof. In the recesses 24side ypieces 25 are mounted for longitudinal adjustment, the upper surfaces of the side pieces being flush with the upper surface of the gate 21. The lateral portions of the gateA 21 and the outer edges of the side pieces 25 are slidably received in the guides 20. The inner ends of the side pieces 25 are cut away and rounded, as

shown at 26, and it may therefore be saidk that the gate 21 is out away at its inner corners, to leave openings at the inner corners of the gate, adjacent to the periphery of the roll 23 of the briquetting press. Securing elementsr 27, such as bolts, are mounted in the-lateral portions of the gate 21, and are received in elongated slots 28 formed in the side pieces 25 of the gate. By loosening the bolts 27, the side pieces 25 may be adjusted in and out, with respect to the roll 23, to vary the size of the openings at the innercorners of the gate 21, adjacent to the peripheryof the roll 23. The gate421 slides in alignment with one of the prolonged diameters A-B of the roll 23, as shown in Fig. 1. `Because the wall 15 of the hopper 14 is vertically adjustable, through the instrumentality of the means shown at 16, the wall 15 may be made to cooperate properly with the upper surface of the gate 21.

Because the gate 21 is adjustable inv and out, in line with the diameter A-B of the roll23, the gate is disposed at right angles to themixtu're, as lthe mixture flows downwardly across the inner edge of the gate, and the resistance offered tothe downward movement of the mixture can be regulated, as the4 gate 21 is moved in and out, better than would be the case ify the gate were disposed otherwise than in line with the axis lr-B. Since the side members 25'of Fig. 6 can be adjusted in and out, the distance between the inner ends ofthe side members and the periphery of the roll 23 can beadjusted, and the friction of the downwardly moving material at the sides lofthe hopper 14 can be regulated, thereby bringing about an even downward ow of the vinass of material at the sides of the mass and at the center of the mass, the material ybeing distributed uniformly and fairly to the rolls 23 and 29 of the briquetting press. lThe rolls 23v and 2,9 of the briquetting press have the usual cups 3() for the formation of the briquettes, and the driving mechanism 31 for the rolls may be of the usual interineshing-gear construction indicated in Fig. 3,V and calling for no extended description.

Any suitable means may be provided for ture.

adjusting the gate 21 in and out. Thus, as shown, but not of necessity, a link 32 is connected by a removable pivot element 33 with the outer edge of the gate 21, the link being pivoted to an arm 34; on a shaft 35 mounted to rock in a segment 36 on a suport 37, a hand lever 38 being secured to the shaft 35, and the hand lever carrying latch mechanism 39, adapted to cooperate with the segment 36.

The operation of the press has been dealt with hereinbefore, step by step, but by way of rsume, it may be stated that the divided lcoal and the binder are introduced into the hopper-head 10 by the mixing device 1. The mixed material moves downwardly through the hopper 14, across the inner edge of the gate 21, and the briquetting is brought about by the cupped rolls 23 and 29 of the press, these rolls being rotated by the mechanism shown in Fig. 3 at 31.

The inward and outward movement ofthe gate 21, by means of the hand lever 33 and associated parts, need not be gone' into, sincev it will be understood readily when Fig. 1 of the` drawings is casually inspected.

Having thus described the invention, what is claimed is 1 1. Ai coal briquetting pressy embodying cooperating rolls journaled for rotation, a hopper above and discharging between the rolls, and a gate slidable at the lower end of the hopper, at an acute angle to the line of flow throughthe hopper, the inner corners of the gate being cut away, adjacent to one roll, and at the sides of the hopper.

2. A coal briquettingpress embodying cooperating rolls journaled for rotation, a hopperabove and discharging-between the rolls, and a' gate slidable at the lower end of the hopper, at anracute angle to the line of flow through the hopper, in alignment with -a prolonged diameterof one roll, the inner corners of the gate being cut away, adjacent to said roll, and at the sides of the hopper.l v Y 3. A coal briquetting press embodying cooperating rolls journaled for rotation, a

hopper above and discharging between the rolls, and a gate slidable at the lower end of the hopper, towardand away from one roll, side pieces adjustable on the gate, tQ- ward `and away 7from'said roll, and means for holdingithe side pieces in adjusted positions on the gate, thereby to leave spaces at the inner corners of the gate, adjacent to said roll, and at the sides of the hopper.

In testimony that I claim the foregoing as my own, I have hereto affixed my signa- EMORY E. Jones.
